OFFER Juniper JN0-660 PDF and JN0-660 VCE Full Version (1-10)

QUESTION 1
Click the Exhibit button. Customer A is complaining that CE1 and CE2 cannot form an OSPF adjacency across your LDP Layer 2 circuit. The physical topology of the network is CE1-PE1-P-PE2-CE2. PE1’s loopback is 192.168.5.1, P’s loopback is 192.168.6.1, and PE2’s loopback is 192.168.7.1Referring to the output in the exhibit, what is the problem?

A.    mismatched virtual circuit ID values
B.    mismatched interface encapsulations
C.    incorrect PE-CE interface configuration
D.    extended LDP neighbor not established

Answer: A

QUESTION 2
You are a network administrator in charge of configuring CoS for your network. Your network includes a voice application with strict latency requirements, so that any packets delayed by more than 75 ms are effectively useless. When configuring the scheduler for this application, which feature ensures that you do not waste buffer space?

A.    rate-limit
B.    adaptive
C.    latency-limit
D.    temporal

Answer: D

QUESTION 3
In your network, customers are complaining about the performance of voice traffic.
Which command displays the number of packets dropped due to the drop profile configured?

A.    show interfaces queue ge-1/0/0
B.    show interfaces terse
C.    show class-of-service interface ge-1/0/0
D.    show class-of-service forwarding-class

Answer: A

QUESTION 4
You are asked to design a Layer 2 VPN service between service provider networks that needs Ethernet transport capabilities. The VPN should support two or three endpoints. Which Layer 2 VPN technology should you propose?

A.    LDP-signaled VPLS
B.    BGP-signaled VPLS, using the RFC 4448 Layer 2 frame format
C.    LDP Layer 2 circuit, using the RFC 4448 Layer 2 frame format
D.    BGP Layer 2 VPN

Answer: B

QUESTION 5
Your router is receiving four BGP route advertisements for the 192.168.100.0/24 network. By default, which route becomes active?

A.    Route A, which is learned through EBGP with an AS path of 8001 and a MED of 175.
B.    Route B, which is learned through IBGP with an AS path of 9900, a MED of 150, and an IGP
cost of 15.
C.    Route C, which is learned through IBGP with an AS path of 8001, a MED of 100, and an IGP
cost of 10
D.    Route D, which is learned through EBGP with an AS path of 9900 and a MED of 200.

Answer: C

QUESTION 6
You just added route reflectors to your network and you find that all of your VPN routes are hidden on the route reflectors. What three solutions can you use to solve this? (Choose three.)

A.    Use rib-groups to add IGP routes to inet.3 and/or inet6.3 on all of the client routers.
B.    Add MPLS LSPs between the route reflectors and their client routers.
C.    Apply a next-hop-self export policy on each of the route reflectors.
D.    Use rib-groups to add IGP routes to inet.3 and/or inet6.3 on the route reflectors.
E.    Add a static default route to inet.3 and/or inet6.3 on the route reflectors.

Answer: BDE

QUESTION 7
An administrator wants to block the re-advertisement of the 10.10.255.6 FEC to all LDP neighbors while still advertising the local router’s loopback address. What will accomplish this?

A.    Option A
B.    Option B
C.    Option C
D.    Option D

Answer: B

QUESTION 8
Click the Exhibit button. Referring to the exhibit, which two statements are true? (Choose two.)

A.    The VPN uses LDP signaling for VPLS services.
B.    The VPN uses BGP signaling for VPLS services.
C.    The PE and directly attached CE are multihomed.
D.    There are only 2 PEs with VPN membership in the network.

Answer: AD

QUESTION 9
You operate a Layer 3 VPN for multiple customers. To support advanced route filtering on your PE routers, you must advertise more than one BGP community on advertised VPN routes to remote PE routers. Which routing-instance configuration parameter supports this requirement?

A.    vrf-import
B.    vrf-export
C.    vrf-target import
D.    vrf-target export

Answer: B

QUESTION 10
You are trying to establish an EBGP peering with a neighbor that is not in the same subnet.
What configuration parameter, when accompanied with a supporting import policy, can you use to resolve the issue and maintain multipath functionality?

A.    multihop
B.    accept-remote-nexthop
C.    multipath
D.    include-mp-next-hop
